Study Notes

Encrypting data is important to keep it secure, especially at rest on storage drives.
Full disk encryption (FDE) encrypts entire drives for maximum security.
Individual files or folders can also be encrypted, often built into file systems like NTFS on Windows.
USB drives should be encrypted due to easy loss.
Decryption keys should be managed carefully to avoid loss.
Active Directory can store decryption keys for backup and recovery.
Complex passwords are essential for strong security, with a focus on entropy (unpredictability).
Passwords should be 8 characters or longer, contain a mix of uppercase, lowercase, and special characters.
Password policies encourage regular expiration and password rotation.
Default usernames and passwords should be changed during setup for device security.
UEFI BIOS passwords secure access to device configurations.
Passwords protect access to sensitive Personally Identifiable Information (PII).
Privacy filters and careful monitor placement can protect sensitive data from prying eyes.
Access to resources should be granted based on job function and need.
Administrative access should not be granted to everyone in an organization.
Group permissions should be assigned to users based on job function.
Network access can be restricted during certain hours.
Unnecessary accounts can be disabled.
Default settings and accounts should be changed for security reasons.
Account lockout thresholds prevent brute force attacks.
Interactive logon policies can lock the system after a period of inactivity or user absence.
AutoRun feature, which automatically executes files on removable media, was removed for security reasons in Windows 7 and later.
